LeBron James is unlikely to accept the Cavs' offer of a contract extension this off-season.

While attending an event to unveil his latest sneaker from Nike, James hinted that he would like to explore free agency in 2010.

"I signed a contract in 2006 with an option," James said, according to the Associated Press. "It would make no sense for me to sign that contract if I didn't keep my options open. I'll let you fill in the blanks."
